Title: Roofing element
Inventor: KREUZBERGER BRUNO
IPC: E04D13/16
Filed: 1984-03-23
Abstract: A description is given of a roof element having rafters (1) which can be fitted at intervals, heat-insulating panels (11) which can be fastened on said rafters, and panels (16) provided for the internal cladding. In order that individual elements can be industrially prefabricated and that not only the construction of a roof composed of these elements be simplified, and thus cheaper, but also that a specific internal cladding of the rafters be dispensed with, with the result that considerable simplifications are possible, the invention provides that the rafters (1) are industrially prefabricated and have the cross-sectional form of a double-T girder having a web (2) and two transverse pieces (3), and that a similarly prefabricated, internal panel (16) can be introduced and fastened between in each case two rafters (1), in the angle (15) formed between the web (2) and the lower transverse piece (3). <IMAGE>
Patent DE-3425792-A1 (DE)
Title: Electronic protection circuit for machines and electric motors having a constant current consumption
Inventor: VELROYEN HANS-JOSEF
IPC: H02H7/08
Filed: 1984-07-13
Abstract: An electronic protection circuit for machines and electric motors having a constant current consumption. This protection circuit originates from the field of electronic digital technology. This protection circuit allows machines or electric motors, or both at the same time, to be protected against destruction and overloading. This is achieved purely electronically, by monitoring the motor rated current, rather than via pressure sensors or the like. For example, a pump can be protected against destruction resulting from dry running. The protection circuit can be used for large and small pumps, high-pressure pumps and fan systems. In the case of a large pump, said pump is generally protected via a plurality of pressure sensors. In addition, motor protection is provided by overcurrent protection switches. The circuit which I have developed has the advantage that both machine parts are monitored and protected simultaneously. In the case of a pump system, if, for any reason, the water pressure head is depleted (dry running), the motor is switched off within the set time of 1-10 seconds, via the reduced motor current. The same applies in the case of a blocked pump wheel, where the motor current is greater than the rated current. Switching off likewise occurs in the case of the shaft or coupling breaking down, where switching off occurs on the basis of the idle current. The limits for switching off can be set in wide ranges, using regulators. <IMAGE>

Title: Motor vehicle with an internal-combustion engine and a power take-off, independent of the fuel of the internal-combustion engine, for driving at least one auxiliary unit
Inventor: FOERSTER HANS-JOACHIM PROF DR
IPC: F02B67/04
Filed: 1984-11-17
Abstract: A motor vehicle is provided with a drive axle, drivable from an internal-combustion engine, and auxiliary units such as generator, power steering pump, compressor, lubricant pump etc., and with a power take-off with energy supply independent of the fuel of the internal- combustion engine, for driving at least one of the auxiliary units. In order to restrict or to prevent the consumption of fuel in overrun conditions, but nevertheless to be able to drive and re-accelerate auxiliary units, an engine-dependent power take-off derived from the internal-combustion engine is connected in parallel to the independent power take-off. The independent power take-off is derived from the drive axle and is switched off in traction operation. In overrun conditions, the fuel supply of the internal-combustion engine is both switched off and its crankshaft speed held at a reference value approximating to the idling speed by a controllable induction coupling connected into the independent power take-off.

Title: Guide device for a laser beam for three-dimensional workpiece machining
Inventor: ROEDER WALTER
IPC: B23K26/08
Filed: 1984-12-03
Abstract: In a guide device for a laser beam (17) multiply deflected at 45 DEG mirrors, at least six controlled movement axes (X, Y, Z, 4, 5, 7) are provided, two of which (5, 7) are horizontal swivelling axes (11, 14), one of said swivelling axes (14) being assigned to the laser head (15). Not only in the case of two-dimensional cutting operations but also with three-dimensional cutting operations can it be ensured, by appropriate adjustment of the swivel angles ( alpha ,  beta ) at the swivelling axes (11, 14) and by a sufficient distance between the two swivelling axes (11, 14), that the cutting point (27) on the workpiece (26) is always located vertically below the Z-movement axis, whereby the movement programming of the device is simplified. By setting equal swivel angles ( alpha ,  beta ), simplified arcuate cutting operations can be executed on horizontal workpieces by rotation about only one movement axis (4). With an arrangement of four swivelling axes, simplified arcuate cutting operations can also be performed on non-horizontal workpieces. <IMAGE>

Title: FM-PLL demodulator circuit with adjacent-channel noise compensation
Inventor: MAURER ROBERT PROF DR ING
IPC: H03D3/24
Filed: 1985-07-18
Abstract: The invention relates to an FM-PLL demodulator circuit with adjacent-channel noise compensation which contains a voltage-controlled oscillator. In the invention, the input signal is divided between two arms of a quadrature PLL demodulator which in each case contain a multiplier. The output signal of the oscillator is fed as a second input signal to the multiplier in the first arm, while the phase-shifted output signal of the oscillator is fed to the multiplier in the second arm. The output signal of the multiplier in the first arm is forwarded to an input of a summer to whose other input the output signal of a filter circuit located in the second arm and connected downstream of the second multiplier is fed. The filter circuit in the second arm and the phase shift of the oscillator output signal activating this arm must be selected in such a way that adjacent-channel suppression is carried out at the output of the summer.
Patent DE-3526175-A1 (DE)
Title: Input changeover switch for a satellite receiving circuit
Inventor: OHLER MICHAEL DIPL ING
IPC: H04B1/18
Filed: 1985-07-23
Abstract: In satellite television, reception signals are received with right and left polarisation and one signal or the other must be fed with the aid of a changeover switch to a converter for processing. In the invention, the changeover switch is formed by two RF transistors which can be switched on and off, only one of which is in each case in the through-connected active condition. The operating currents of the RF transistors are fed via auxiliary diodes in the collector circuit which, in the zero-current condition, effect an additional high stop-band attenuation. PIN diodes can be used as the auxiliary diodes which simultaneously serve as control components for automatic gain control when the RF transistors are connected along with the power supply via the PIN diodes to a separate further power supply.

Patent DE-3540559-A1 (DE)
Title: Safety crank for a winch drive or the like
IPC: B66D1/06
Filed: 1985-11-15
Abstract: A safety crank for a winch drive or the like, comprising one or more ratchet wheels lying in a housing and provided with teeth and several spring-supported pawls engaging in the teeth, is designed according to the invention in such a way that at least two pawls (4) engage simultaneously and completely in the teeth (7) and are supported in each case on a tooth face (13), the number of teeth (7) corresponding to an even multiple of the number of engaging pawls (4). In this arrangement, four pawls (4), for example, can be provided which are arranged at equal angular distances from one another and of which in each case two diametrically opposite pawls (4) engage simultaneously in the teeth (7) of the ratchet wheel (2), while the other two pawls (4) are supported with their backs on tips of the teeth (7). On the one hand this ensures that the load acting on the corresponding engaged teeth (7) is halved just as the load acting on the pawls (4) is halved, and on the other hand the return distance of the crank (11) corresponds to the range which has to be covered until the next opposite pawls (4) come into engagement. Here, the ratio of the number of engaging pawls (4) to the number of pawls (4) not in engagement determines the return distance. <IMAGE>

Title: Process for producing utilisable products downstream of a flue-gas desulphurisation
Inventor: HOELTER HEINZ DIPL ING
IPC: C02F11/06
Filed: 1985-12-20
Abstract: It is known that downstream of flue-gas desulphurisation systems, a gypsum-like material is produced. It is also known that ash is produced downstream of power stations. Ash and gypsum and other additives in many cases form the basic raw material for a final product which is used in the cement industry and in mining and tunnel construction. Since river water and industrial water which are polluted with ammonium compounds are used for flue-gas scrubbing, it is necessary to subject the mixture comprising raw gypsum and the other additives to a thermal process, the water being evaporated together with the ammonium compounds which are environmentally polluting. In order to eliminate this disadvantage, it is proposed according to the invention to feed the ammonia-containing exhaust fumes released from the process water into the fire region of the fossil fuel-fired combustion boiler. The scrubbing water is inoculated with solutions of alkali metals or of alkaline earth metals, aerated and the resulting ammonia-containing exhaust fumes are transferred to the furnace region of the boiler.
